目的：研究速效救心丸对实验性心肌梗死大鼠心脏的促血管新生作用。方法：利用SD大鼠冠状动脉结扎法结造成急性心梗(AMI)模型，观察速效救心丸对AMI大鼠心梗面积及梗死边缘区心肌微血管密度的变化。结果：速效救心丸高、低剂量组与模型组梗死面积比较，均有极显著性差异(P<001)，且有一定的剂量依赖性，与阳性对照组作用相似；速效救心丸高、低剂量组与假手术组相比较，其心肌梗死边缘区的平均血管面密度(MVD)均明显增多(P<005)，速效救心丸高剂量组与阳性对照组作用相似，但速效救心丸高、低剂量组比较无统计学意义上的差异(P<005)。结论：速效救心丸对实验性心肌梗死大鼠的心脏有明显的促血管新生作用。
Objective: To study the effect of Suxiao Jiuxinwan on angiogenesis in experimental myocardial infarction rats. Method: The animal model was established by ligation of anterior decending coronary artery and the infarction areas as well as microvascular density (MVD) in the marginal infarction area of the myocardial infarction rats were observed. Result: Infarction areas in high dose and low dose Suxiao Jiuxinwan groups were significantly different from that of model group (P<001), and this effect was similar with the positive model group and had the dosage dependent speciality. The microvascular density (MVD) of marginal infarction areas in Suxiao Jiuxinwan high and low groups was much more elevated than that in the sham group (P<005), and the effect of Suxiao Jiuxinwan high group was similar with that of the positive control group. But the difference between the Suxiao Jiuxinwan high and the low goups was not significant. Conclusion: Suxiao Jiuxinwan has the obvious effcet on angiogenesis in eperimental myocardial infarction rats.
